Millennium Minerals Limited advised that a major new round of resource in-fill and extensional drilling has commenced from newly-established underground drilling platforms at the Bartons deposit, part of its 100%-owned Nullagine Gold Project in Western Australia. The Bartons Underground development has now been completed to the 225m level, with the drilling program designed to in-fill deeper portions of the Mineral Resources and allow conversion of the next five development levels into Ore Reserves. With the underground resource remaining open at depth, the drilling will also test for extensions of the deposit to a depth of 200m below the currently-defined mineralisation. In addition to the resource in-fill and extensional drilling program at Bartons, Millennium will also undertake exploration drilling to target a prominent coincident electromagnetic (EM) and gravity anomaly located 350m to the north-west of the Bartons Underground mine. This EM conductor is highly anomalous within the broader Nullagine Project area, and could be associated with the stratigraphic or structural position of potential Volcanogenic Massive Sulphide (VMS) mineralisation. While the Nullagine Project has never previously been thought to host volcanic rock units, recent mine development at Bartons Underground has confirmed the presence of bedding-parallel igneous rocks within the footwall. Confirmation of the presence of igneous rock units in close proximity to a coincident EM/gravity anomaly makes this a compelling exploration target for Millennium. The company is currently undertaking geological work to identify and assess the favourable stratigraphic horizon for the development of VMS mineralisation at Bartons. The VMS exploration program is being supported by specialist base metals consultant, Jon Hronsky, and is being co-funded by a West Australian Department of Mines, Industry Regulation and Safety (DMIRS) Exploration Incentive Scheme grant of up to $150,000. The company also reported preliminary results from a recently completed gravity survey over the Golden Eagle, Five Mile, Middle Creek and Camel Creek Mining Centres at Nullagine. The gravity survey has significantly enhanced Millennium's understanding of the controls over gold mineralisation in the district, showing that mineralisation across the project area is strongly coincident with the edges of gravity anomalies. The results provide Millennium with an important new dataset to assist with exploration targeting. Exploration at Nullagine has historically focused on geochemical anomalies. However, the gravity data shows a compelling correlation with the gold mineralisation discovered at Nullagine to date. A number of distinct gravity features have been identified in areas that have not previously been tested by drilling. Several of these features are located beneath cover, in areas where surface geochemical anomalism may not be present. In light of these compelling results, drill programs are now being planned to test the most prospective gravity targets for gold mineralisation.
